Undisciplined Players

In the earliest rounds, with or without raises, in or out of best position, should I play Kx? I used to, but I don't any more and of course there's a king in the flop.

You will fold the winning hand quite often in poker. Playing Kx or even Ax from any position (but especially oop), can get you into trouble when you hit it on the flop. You can easily be outkicked.

If I have Ax, and the table is, for example, 3-7-3-4-9, and it's checked to the river around to me, is someone slow-playing, or if I put a raise in will I take the pot?

[/ QUOTE ]
It really depends, someone could be slowplaying a strong hand, hit 2nd pair, or have nothing with a missed draw. More info. about how the hand played out would help. When you say "checked around", it sounds like there are several players in the hand, so I'd proceed carefully and most likely would check having hit nothing, and be happy if my A kicker took it.

In another place I played a non-dealing player would reach over and count the chips to see.

I could be wrong, but that sounds like a big no-no. Some home games can be fairly loose with the rules, and I don't like to be a nit, but technically I believe you can't even ask for a count of the pot. In the nlhe home game I play in, I sometimes lose track of the size of the pot and just eyeball it. I can usually come up with a reasonably accurate count by staring with the larger denomination chips and working my way through it. It doesn't have to be exact, just close enough that you're bet size accomplished what you meant.
